* Colin Kaepernick, who could be in line for a massive contract extension, is under investigation – but not charged with anything – for a bizarre incident in Miami that involves two other NFL players, a woman, nudity, and allegedly, hits from the bong. Hey San Francisco, what’s up with all these police investigations?

* Aldon Smith, who has been a fear-inducing edge rusher for three years, racking up 42 sacks in 43 games, got arrested at the airport for allegedly saying “bomb” to TSA agents. He had DUI arrests in 2012 and 2013, and has been to rehab. Police think he had been drinking the day of his airport arrest (but wasn’t intoxicated).

Since losing the NFC Championship games in the final moments, it’s been a rough three months for the 49ers. And it’s likely only going to get worse.

Some key parts in this offense are getting old. Anquan Boldin turns 34 in October, Frank Gore turns 31 in May, and Vernon Davis is 30. One of the best inside linebackers in the league, NaVarro Bowman, is expected to miss half the season after tearing an ACL/MCL against Seattle. (He is “ahead of schedule” but if you expect him to be playing in Week 1, you’re crazy.)

The schedule is unforgiving – trips to the Saints, Broncos, Cowboys and Giants. The NFC West might be the best in football, especially with St. Louis on the rise, and Arizona getting chatter as a darkhorse Super Bowl contender.
